I'm trying a Sorcerer from the start and the new costs for the ray spells are really great. Casters can finally play as casters from the start, instead of having to trust Master's Touch and a good axe.
However, from the point you get Maximize or Empower things start to get bad again. I mean, paying 6 for Scorching Ray really allows you to play as a true caster, but paying 6+25 for a double damage Scorching Ray just spoils the whole spell cost changes. Of course I can play without metamagic, but this is just not right. Double damage should translate into double cost, or something like that..
Releasing Update 9 with all those nice spell changes but keeping matamagic applied as an added cost instead of percent is a bad move (IMO of course).
